Insert in the Drawing

Click on the BeamViz Tool icon .
Click on the drawing in the approximate plan location where you would like the light to hang.
Drag the beam edge or focus point (indicated by a locus) to the point you would stand when focusing the light. The size and shape of the beam will change accordingly.
Alternatively, you can insert the beam at its focus point and drag the boxed control point to a hanging position. Y our cursor will change to a double arrow when it is over the control point.
You can also use nudge (shift+arrow) or grid nudge (cmd/ctrl+shift+arrow) to fine tune the beam based on your fixed parameter (focus location or fixture location). The default is Light Location.
